1.[Regulating effect of pineal gland peptides on development of T-lymphocytes in CBA aging mice: role of microenvironment of immune system organs and neuroendocrine factors].
Labunets IF;Butenko GM;Khavinson VKh;Magdich LV;Dragunova VA;Pishel' IN;Azarskova MV Adv Gerontol. 2003;12:111-20.
Studies were undertaken on the development of T-lymphocytes in adult and old CBA mice and its changes at aging after injections of pineal gland peptides. It was shown that in old mice the disturbances of T-cells differentiation are registered in bone marrow, thymus, spleen and characterized by the changes of lymphocyte markers expression, migration and proliferation of cells. In old mice FTS titer, melatonin and testosterone levels decreased, the balance of noradrenalin and serotonin in hypothalamus and the cell composition of microenvironment immune systems organs impaired. After chronic (18 mo) administration of the pineal gland preparation epithalamin the amount of stromal cells-precursors, CD4+ and Mac-1(+)-cells in old bone marrow increased, improved the migration of T-cell precursors from bone marrow to thymus and their proliferative potential. The proportion of CD3+, CD4+CD8-, CD4-CD8+, Mac-1(+)-cells in old thymus increased, while that of CD44(+)-cells decreased. The proportion of CD4-CD8(+)-cells in spleen increased. The most number of indices and their balance showed a pattern of adult mice. In old mice after epithalamin the balance of amines in hypothalamus improved, concentration of melatonin in pineal gland, testosterone and FTS titer in blood increased.
2.[Peptides and CCL11 and HMGB1 as molecular markers of aging: literature review and own data].
Khavinson VKh;Kuznik BI;Tarnovskaia SI;Lin'kova NS Adv Gerontol. 2014;27(3):399-406.
Cytokines CCL11 (eotaxin) and HMGB1 (alarmin1) are molecular markers of ageing and neurological, cardiovascular and immune diseases. Created in St. Petersburg Institute of Bioregulation and Gerontology short peptides are known to regulate gene expression and protein synthesis. They promote the mortality decrease and slowdown the development of pathology in the elderly. The article presents the proposed role of dipeptide vilon (Lys-Glu) and tetrapeptide epitalon (Ala-Glu-Asp-Gly) in CCL11 and HMGB1 genes regulation as activators of their expression. Geroprotective action of vilon and epitalon probably realizes in suppression of these genes.
3.[Administration of epithalamine in the treatment of unstable glaucoma of different types after normalization of intraocular pressure].
Egorov VV;Sorokin EL;Smoliakova GP Vestn Oftalmol. 2003 Jan-Feb;119(1):5-7.
The treatment effect and clinical efficacy of epithalamine solution was studied on 28 patients (42 eyes) with unstable glaucoma and normalized intraocular pressure (IOP). Epithalamine belongs to the group of cytomedines and it has a modeling effect on the functional activity of the simpatico-adrenaline system, adrenal cortex and anti-oxidizing activity. The clinical study showed that the use of epithalamine solution resulted in normalization of the biochemical activity of the neuro-humoral triphism (adrenaline, norepinephrine, and hydrocortisone). It leads to an increased diameter of arterioles of the bulbar conjunctiva and of the optic disk as well as to a decreased degree of congestive angiopathy and of intravascular aggregation of erythrocytes.
